FREDERICK OTT, OF SOUTH BETHLEHEM, PENNSYLVANIA.

LOOM.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed May 1, 1907. Serial No. 371,305.

To all whom it may concern:

Be it known that I, FREDERICK O'r'r, of South Bethlehem, in the county of Northampton and State of Pennsylvania, have in vented certain new and useful Improvements in Looms, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in cross-weaving looms, as, for example such as are employed in the production of veiling or gauze weaving.

It comprises means for displacing the binder or whipping threads laterally with respect to the standard threads in alternate directions whereby 'a cross weave is formed.

Although I have shown several convenient embodiments of my invention, it should be understood that it is not confined to them, since other modes of performing the operations will readily suggest themselves.

In one form it comprises a movable comb of needles arranged to be reciprocated vertically, and also to be reciprocated horizontally by means of a screw thread, which is given a half rotation in alternate directions for each traverse of the shuttle through the shed. The binder or whipping threads are carried by the needles, and twisted about the respective standard threads alternately from opposite sides. In this form the warp threads pass through a set of stationary reeds before passing to the needles.

In a modified form, the comb of needles is arranged to be reciprocated vertically, and also to be reciprocated bodily horizontally but without rotation of the screw thread. It is also obvious that thestationary reed could be reciprocated horizontally and the comb vertically to accomplish the desired result.

In the accompanying drawings, Figure I, is a vertical section through a loom showing one form of my invention applied thereto in which the screw is given a half rotation in alternate directions to move the needles. Fig. II, is an enlarged front elevation of a portion of the needle comb, screw and reeds. Fig. III, is an enlarged plan view showing a portion of the screw and the needles engaged thereby showing their staggered relation. Fig. IV, is a view similar to Fig. I, of a modification in which the needle comb is reciprocated without the rotation of the screw thread. Fig. V, is a partial plan view of the modification shown in Fig. IV. Fig. VI, is an enlarged sectional view taken on the line VII, VII, in Fig. IV.

In said figures,the lay 1, is mounted upon swords 2, pivoted at 3, and oscillated by means of the pitman 4, connected with the crank shaft 5, in the well known manner. The binder threads 8, and 9, which are fed from the beam 6, and the standard thread 10, fed from the beam 7, pass through the stationary reeds 11, and then through the reeds 12, mounted upon the lay 1, one binder thread and one standard thread passing through each opening in the reeds.

Mounted to reciprocate vertically upon a pair of rods 14, one at each end of the machine is a frame 15, which carries the needle comb 16. The needles 17, are secured to the back of the comb in any approved manner. At each side of the machine a bracket 18, is located which forms a bearing for one end of the screw 20. This screw is provided with threads which are beveled at about the angle of 40 degrees and maintain the needles 17, in staggered relation as clearly shown in Fig. III. Upon one end of the screw 20, is a small pinion 22, adapted to be engaged by a rack 24, which is formed on one end of a rod 25, pivotally secured to one arm of the gear 26, this gear is driven by a similar gear 27 secured to the crank shaft 5. The ratio of the gears 26, and 27, is such that the screw 20, is given a semi-rotation in alternate directions for each rotation of the crank shaft 5. The frame 15, is sustained by means of a chain 30, at each end thereof, said chain passing over pulley 19, and then secured to a crank arm 31, on the shaft 5. By this con struction, the frame 15, is reciprocated at each rotation of the crank shaft 5.

The sequence of operation of the elements above set forth is so timed that when the needles 17 are in their lowermost position the screw 20, is given a semi-rotation. Each one of the binder threads 8, and 9, passes through an eye in one of the needles 17. When the screw 20, is turned the needles are all shifted to one side or the other in accordance with the direction of rotation of said screw'thus displacing the binder threads laterally with respect to the standard thread. Upon the further rotation of the crank shaft the needle comb is drawn upwardly by the chains 30, and the binder threads are thereby twisted about the standard thread. l/Vhen in the uppermost position the shuttle is passed through the shed and the filling thread is then beat up by the lay in the well known manner. At the next rotation of the crank shaft and when the needles are in their lowermost position they are moved transversely in the opposite direction from that of the previous rotation and thus when moved to their uppermost position twist the binder threads about the standard threads in the opposite direction.

In the modification shown in Figs. IV, V, and VI, the frame 40, is suspended by means of chains 41, connected with the crank shaft 5, in the same manner as above set forth, and the needle comb 42, is mounted to reciprocate in the frame 40. Upon this frame 40, is secured a bracket 43, which engages the collars 45, and 46, on one end of the screw 44, this screw being slidably mounted in the bracket 43, on each side of the loom. The engagement of said collars 45, and 46, with bracket 48, maintains screw in correct rela tion with the needle comb during the reciprocation of the latter in a vertical direction. The frame 40, is provided at each end with a long sleeve 47, which slides upon the rod 48, mounted upon the side frame 49, of the loom. Secured to one end of the needle comb 42, is a right angled rod 50, which eX- tends outwardly and upwardly through a slot in the bracket 32, and is adapted to be engaged by the chamfered end of a rod 51, secured to an eccentric 52, mounted upon the shaft 53, said shaft being journaled in bearings 54 (best shown in Fig. V). The outer end of the rod 51, slides upon a guide 55, attached to the outside of the bracket 32. Below the needle comb and having one end secured thereto by means of a pin 56, is a spring 57, having its other end secured by means of a pin 58, to the frame 40. The pin 56, passes through a slot 59, in the frame 40, which allows the comb to reciprocate longitudinally with respect to the frame, and also limits the motion of comb 42, in the frame 40. Upon the crank shaft 5, is a gear 60, adapted to mesh with the gear 61, mounted upon shaft 53. The ratio of the gears 60, and 61, is such that the needle comb 42, is reciprocated in alternate directions for each rotation of the crank shaft 5. This reciprocation takes place when the needles are in their lowermost position and the binder threads are twisted alternately on one side and then on the other of the standard thread in a manner similar to that above set forth. It will be understood that in -this modification the lay and reed secured thereto are of ordinary construction.

Mounted between the needles and the beam from which the threads are fed is a reed frame 62. Between each of the strips of this reed frame a binder thread and a standard thread are passed. In this modification this reed frame is maintained in stationary position.

be reciprocated when the needles are in their lowermostposition instead of reciprocating the needles, as the object of the device is merely to displace the binder threads transversely with respect to the standard threads, the binder threads being. each held in position by one of the needles, whereas, the standard thread passes from one reed frame to the other. I

Having thus described my invention, I claim: I
